I got a MBP just last month, the battery capacity has decreased to 97%.

However, recently, when I turn my MBP on and I check Coconut Battery, the battery capacity remains at 97% but my battery charge is only at 20%. And I kind of leave my MBP plugged in all the time usually at 100% charge, I have no idea why the battery charge keeps dropping and if this is normal.

As in after I charge it up, turn it off overnight, turn it on the next morning, the battery charge is only 20% and it doesn't charge until I unplug it and plug it in again.

Is this normal? And I'm sorry if this is a duplicate thread, but all the threads I've found is about the decrease in battery capacity but not drop in battery charge.
 
Thanks for the link. I'll re-calibrate my battery and see what happens!
